' In Germany June 25, 1931 3 Claims.

Methods are already known of making containers in the form of cartons or the like, intended to hold cigarettes or like goods, by means f formers. It has previously been proposed to arrange the formers serially on an endless belt or another form of conveyer track, at suitable dista'ncesapart, so that in the course of their travel they contact with the blanks for the carton or the like, the carton being shaped on the former during the travel of the latter. In this method the problem arises of removing the finished carton from the former. Various suggestions have been made for solving this problem. Owing to the fragility of the work ithasbeen proposed. that the finished cartons be blown off the formers by means of compressed air; this, however, necessitates a troublesome compressed air apparatus, control etc. On the other hand, it has been proposed. to remove the carton from the formers by meachincally operated removing members, in such manner that the removal members which engage behind the cartons on the formers are moved in the operative direction of the formers but more'rapidly than the latter. Here again an inconvenient form of mechanism is necessitated, without its being possible to ensure that the fragile article will not be damaged.

Accordingto the present invention the former, which is carried in known'manner by a chain or the like after the carton has been shaped, is guided in a curved path and thereby brought into engagement with removal members which come into position behind the container on the sides of the former; in such manner that in consequence of the curvature of the path displacement of the former in relation to the stationary removal member takes place so as to cause the container to be removed.

In this case there is no necessity whatever for the removal members to be actuated, 'and the arrangement may be such that the removal members are placed tangentially or approximately so in relation to the beginning of the operative point of the curvedpath, so that the engagement with the cartons occurs without any shock.

Two oppositely disposed, bar-shaped removal members which are moved in relation to one another under spring control, are preferably .provided, and between these an extension of the former enters under moderate spring tension.

The removed cartons are deposited in receptacles which are arranged in sequence at suitable distances apart on a conveyer track, so arranged that a receptacle is always opposite. to the removed container.

Two forms of construction of the invention are illustrated in the annexed drawings, in which:-

Fig. l is a side view.

Fig. 2 is a front view from the direction indicated by the arrow in Fig. 1.

Fig. 3 shows a second form of construction, and is also a side view.

Fig. 4 is a front view from the direction'indicated by the arrow-in Fig. 3.

The formers 1 which are four-cornered and rectangular in cross-section are mounted on the supports 2 which are pivotally attached to the horizontal bars 3. On these bars are mounted chain members 4, and in order to ensure rigidity and steadiness three chains are provided which pass over the sprocket wheels 5 which have the form of circular discs andare arranged'parallel to one another in a suitable manner. The arrangement is'such that the formers 1 always retain their horizontal position. The means by which this is-eifected has been omitted from the drawings for the sake of clarity.

The shaping of the carton blank 6 takes place on the former substantially during .the' time when these formers pass through the part of the circular path located at the rightof the vertical centre line in Fig. 1, so that a former, on its arrival at the uppermost position, carries a completely shaped carton.

According to the present invention two stationary removal members are provided which face each other and are mounted on supports 8. These supports are mounted on horizontal rods '9, which'are attached to the frame member 10 by means of screws 11 and slots 12 in such manner as to be capable of longitudinal displacement. In the supports 8, holes are provided I through which pins 13 pass which are screwed into or otherwise attached to the removal 'members '7. The springs 14 wound round these pins between the support 8 and the removal member 7, tend to thrust the two removal members tov wards one another.

The upper ends 7 of the removal members, which are suitably rounded oiT at the edges in question for the sake of easy engagement, are now placed in the path of a former 1 carrying the finished article 6, in such manner that they protrude tangentially at the point where they come into contact with the containers. The former moves with its parts located behind the finishedcarton, between the tworemovalmembers whereby it presses the latter slightly apart while compressing the spring 14. Consequently, the removal members rest lightly on the respective sides of the former.

Now gentle removal of the work from the former begins, because the latter moves on its further circular path relatively to the stationary removal members so that the carton is removed.

This removing operation is complete when the former has arrived at the lowest point in its circular path.

In order that the articles removed from the former may be deposited in an ordeixy fashion and further despatched, a conveyor chain 15 is provided which is indicated by a chain line in Fig. 2. This conveyer chain is moved in the direction indicated by the arrow in Fig. 2. Receptacles 16 for receiving the removed containers are arranged at intervals on this chain. These receptacles are in the form of channels open at both ends, one side wall 1'? being formed as a flap adapted to pivot about the bolt 18. This flap is actuated in such manner that it is lowered when passed to the receiving position and forms an extension of the bottom of the receptacle. When the carton has arrived at the bottom of the receptacle, it is carried along by the other stationary side wall, and the flap 17 is raised in order to hold the work in the receptacle.

' In the form of construction shown in Figs. 3 and 4, the removal members are not designed as stationary bars, but as pressure members which grip the former, whereby these pressure members undergo a vertical rectilinear displacement.

In this construction, the formers I mounted on the chain members 4 are arranged at suitable positions to co-operate with the chains 19 which are passed over the sprocket wheels 20. On these chains are. mounted pressure members 21 which are provided with rubber cheeks 22 or the like. At the position marked 3: these checks come into contact with the container 6 on the former. While the formers 1 are moved down wardly in the circular path, the cheeks mounted on the chains 19 make a movement corresponding to the vertical lowering of the formers 1. Thereby the container is withdrawn from the former first of all slowly and then more rapidly and deposited in the receptacle 16 of the conveyer chain 15.

It is obvious that the chain 19 must run intermittently in conformity with the downward movement of the formers 1, which can be ar ranged by means of known mechanism, such as elliptic wheels or the like.
